Upon further reflection, I've decided to focus on roofing impropriety as a private mission, and not subject you to it here. Ms. Janet Campbell is the master in this area, and you can read all about it in her blog. Janet is listed under "Trusted Professionals" .
I apologize for letting a personal campaign affect my writing, as I have far too many topics of interest to discuss, and writing time is scarce due to my very intense schedule. Negativity takes a great deal of energy to expose, yet little to create. This is what we're up against.
I will be focused on sustainability issues for a couple of days, but will get back to providing useful roofing information over the weekend. Which roofs are best for cistern use? What are the harmful contaminants, and how do I guard against them? Can I water my fruits and vegetables with water collected from my roof?, etc.
Thanks for spending time with me today, and keep looking "UP".
